The makers of Snickers, Mars Wrigley, has apologised for a product launch which Chinese social media users said suggested that Taiwan was a country.

Videos and pictures of an event promoting a limited edition Snickers bar that was said to be only available in the "countries" of South Korea, Malaysia, and Taiwan went viral on Chinese micro blogging platform Weibo today.

Mars Wrigley published an apology on its Snickers China Weibo account and said the relevant content had been amended.
